“…However, the west and east portions of the Sierra have been largely ignored. Recent visits to the west portion have yielded a number of discoveries of new species (e.g., Campbell and Flores-Villela 2008, Campbell et al 2009, Pavón-Vázquez et al 2011, Feria-Ortiz and García-Vázquez 2012, Campbell et al 2014). This suggests that the diversity of the Sierra Madre del Sur of Guerrero is higher than currently known (Palacios-Aguilar and Flores-Villela 2018), particularly for small and secretive snakes as exemplified by the present work and the recent descriptions of Epictiaschneideri Wallach, 2016, Geophisoccabus Pavón-Vázquez, García-Vázquez, Blancas-Hernández & Nieto-Montes de Oca, 2011, and Rhadinelladysmica Campillo, Dávila-Galavíz, Flores-Villela & Campbell, 2016.…”

A new species of the Rhadinaeadecorata group is described based on two specimens from the Sierra Madre del Sur, Guerrero, Mexico. The new species differs from all other members of the genus Rhadinaea by having: eight supralabials; 149–151 (male) ventrals; 63–77 (male) subcaudals; two large pale nuchal blotches, forming an incomplete collar that occupies two scales laterally and is bissected along the dorsal midline; a postocular pale marking consisting of a well-defined, narrow line beginning behind the upper posterior margin of the eye and extending posteriorly nearly horizontally until connecting with the nuchal blotches; and the dark ground color of the flanks extending to the lateral portion of the ventrals. The large nuchal blotches distinguish the new species from the other members of the R.decorata group, except for R.cuneata and some individuals of R.hesperia (pale nuchal marking one-scale wide in R.marcellae, absent in the other species). The condition of the postocular pale marking distinguishes it from R.cuneata and R.hesperia (postocular pale marking wedge-shaped in R.cuneata, not connected with the pale post-cephalic markings in R.hesperia). Furthermore, the number of subcaudals and the coloration of the lateral portion of the ventrals distinguish it from R.omiltemana and R.taeniata, the remaining congeners found in Guerrero (85–90 in males of R.omiltemana and 91–121 in R.taeniata; dark color of the flanks not reaching ventrals in the former species, occasionally and faintly in R.taeniata). Additionally, a new combination for R.stadelmani is proposed. The new species is the first described in the genus Rhadinaea in more than 40 years.

“…Thus, it is conceivable that these two taxa represent the same species with two color morphs: one predominantly dark and another one with dark crossbands on a red-orange background, as in the polymorphic species Geophis occabus and Geophis brachycephalus (Pavón-Vázquez et al 2011). However, a phylogenetic analysis of Geophis based on several mitochondrial and nuclear genes shows that Geophis lorancai and Geophis turbidus are considerably divergent genetically and not each other’s sister species (Canseco-Márquez et al unpublished data).…”

“…Color codes and descriptions follow Smithe (1975). The diagnosis is based on both the specimens examined and the relevant literature (Bogert and Porter 1966, Downs 1967, Smith and Holland 1969, Campbell and Murphy 1977, Savage 1981, Campbell et al 1983, Restrepo and Wright 1987, Smith and Chiszar 1992, Smith and Flores-Villela 1993, Lips and Savage 1994, Smith 1995, Wilson et al 1998, Pérez-Higareda et al 2001, Myers 2003, Nieto-Montes de Oca 2003, Savage and Watling 2008, Townsend 2009, Townsend and Wilson 2006, Pavón-Vázquez et al 2011, 2013). …”

A new species of the Geophis dubius group is described from the mountains of the Sierra Zongolica in west-central Veracruz and the Sierra de Quimixtlán in central-east Puebla. The new species is most similar to Geophis duellmani and Geophis turbidus, which are endemic to the mountains of northern Oaxaca and the Sierra Madre Oriental of Puebla and Hidalgo, respectively. However, the new species differs from Geophis duellmani by the presence of postocular and supraocular scales and from Geophis turbidus by having a bicolor dorsum. With the description of the new species, the species number in the genus increases to 50 and to 12 in the Geophis dubius group. Additionally, a key to the species of the Geophis dubius group is provided.

Abstract:We record for the first time the recently described snake Geophis turbidus from the state of Hidalgo, Mexico. The species was recorded in cloud and pine forests, and this report extends the distribution of this species approximately 25 km from its previously known occurrence. In this paper, we also report the first description of a juvenile specimen, along with data on the natural history, morphology, and conservation of this species.
